wordpress plugin

Hi,
After a morning of search, I've started a new fresh install of LD + wordpress.

I am WP admin but the plugin link in menu is hidden.
I can display plugin's page "http://localhost/projects/ladistribution/wordpress/wp-admin/plugins"
but I can't edit settings of current plugins "http://localhost/projects/ladistribution/wordpress/wp-admin/plugins.php?page=akismet-key-config"
